WESTCHESTER COUNTY, N.Y. -- Residents of Westchester County are reminded to turn their clocks ahead one hour on Sunday, March 9 for the beginning of daylight-saving time.

Daylight-saving time officially begins at 2 a.m., Sunday and runs from the second Sunday in March through the first Sunday in November.

It was a concept originally proposed by Benjamin Franklin in 1784, according to timeanddate.com. During World War II, President Franklin Roosevelt instituted year-round DST, called "War Time", on Feb. 9, 1942. It lasted until the last Sunday in September 1945.

After 1945 many states and cities east of the Mississippi River adopted summer DST, though after 1945 many states and cities east of the Mississippi River adopted it, but it wasn't widely adopted in the U.S. until the energy crisis in the 1970s.

From 1987 through 2006, daylight-saving time ran from the first Sunday in April through the last Sunday in October. The change was part of the Energy Policy Act of 2005.

Many fire departments also remind residents to replace the batteries in their smoke detectors when they move their clocks forward.
